The "Happy" singer and his wife, Helen Lasichanh, welcomed triplets in early January, Williams' rep confirmed to Vanity Fair.

The couple have not shared any additional details on the gender or names of their babies at this time. But, the triplets part was surprise enough. In September, the pair announced that they were expecting when they attended a Chanel-hosted dinner to celebrate their new fragrance N°5 L'EAU, and Lasichanh showed off a growing baby belly -- but the pair never mentioned that they had three bundles of joy on the way.

Lasichanh, 36, and Williams, 43, are already parents to 8-year-old son, Rocket Ayer, and have been married since 2013. They dated for many years before they married, and Williams once explained to Oprah that when he first met his model, designer future wife, she wasn't even interested in him. He had to stay friends with her for two years before she agreed to date him.
